Micro Ingredients Vitamin D3 50
Checked against public sources on August 13, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Vitamin D is above the adult upper limit. The panel lists 250 mcg vitamin d. NIH gives 100 mcg as the adult Tolerable Upper Intake Level for adults; 100 mcg = 4,000 IU. That is about 2.5 times the limit.
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

| Vitamin D (as cholecalciferol) (D3) | 1,250 (50,000 IU) mcg |

No named laboratory or lot-specific certificate was found for this exact product. A related brand page names no testing issuer and links no product-bound report; its UPC is not published. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.
